One robot removes 2x2 pre-encapsulated contact sets from a punching tool and transfers it directly to the insertion and extraction robot via handshake. Finished parts are removed, taken in the tool and centred and the contact sets inserted. The other half of the tool must be supported during insertion to actuate back-pressure pins for the ejector plate. The finished parts are placed on a buffer workpiece carrier for cooling and conveyance to the second plant section. A small robot removes the cooled part from the buffer and transfers it to a rotary indexing table for assembly and inspection. The parts are centred in the first position and held in the nest via a spring mechanism. Finished parts are removed by active loosening of the spring mechanism, packed in blisters and made ready on a tray stacking system. Quality assurance positions: insertion control, temperature monitoring and electrical inspection (HV, short-circuit, continuity). Functional positions: dispensing, application and welding of membrane, optical control of membrane position, spring assembly (4-fold), optical control of spring position, laser labelling and inspection of the lettering.
